CARBON-REMOVING ATTACHMEN'L ron INTERNAL-COMBUSTION ENGINES.

and use the same.

Thisinvention relates to a combination with an internal combustion engine of a hollow cylindrical chamberadapted to contain a chemical element, and more particu larly to improvements in the means at the outer end of the chamber for admitting air to the chamber which will circulate freely with the chemical element when the engine is in operation. a

Other objects will appear as the description proceeds.

In the accompanying drawings, which form a part of my application,

Figure 1 is' an end elevation of a portion i of an internal combustion engine intake manifold and carburetor, showing my improved carbon removing attachment in section, as applied to the said intake manifold, and

Figure 2 is a transverse sectional view taken on the line 2-2 of Figure 1.

Like characters of reference are used throughout the following specification and the accompanying drawings to designate corresponding parts.

My improved carbon removing attachment is applied to theintake manifold 1, which is connected between the carburetor 2 and internal combustion engine 3, and com rises a cylindrical housing 4, which is s ightly restricted at its lower end and terminates in a threaded end or shank portion 5, where it threads into the said intake manifold 1. The lower portion of the shank 5 is formed with an internal passage 6, and is connected with the interior of the housing 4 by means of the outwardly flared passages 7.

The outer end of the housing is externally threaded and is adapted to receive the removable threaded cap member 8, which isprovided at its center ortion with a threaded stem 9, which terminates at its outer end with a handle portion 10, and

' carries at its inner end a removable spring member 11, which adjustably tensions the valve or washer 12 against the under surface of the cap member 8. A plurality of ports 13 are formed through the cap memher 8 and are normally closed when the engine is idle by means of the valve or washer 12.

Fromthe foregoing description. it will be apparent that when the internal combustion engine is started, the suction in the intake manifold will draw the valve or w sher 12 down against the spring member 11,;so that the ports 13 will be uncovered and the air will be drawn there-through and over the chemical, and through the passages 7 and 6 and in through the intake manifold to the interior of the engine 3, where'the chemicalized air will cut and clean the car bon deposits. It will be noted that the valve or washer 12 is slightly smaller in diameter than the inner diameter of the housing 4, thereby making it possible for the air to be drawn around the same it passes over the chemical andinto the engine.

It will be readily understood that the tension on the sprin member 11 maybe adjusted, as desired, simply turning up or down on thethrea edstem 9. If perchance the spring member .11 should be come broken or in any manner injured, ,the new member may readily be placed in position by removing'the screw 15 and replacin the new member.

My improved attachment may also be applied to the mixing chamber in a carbureter with equally good results.

Many minor changes in detail of construction may be resorted to without departure from the spirit of the invention.

Having thus described my invention what I claim as new and desire to secure by Let? ters Patent of the United States is:

1. In combination, a hollow cylindrical chamber adapted to contain a chemical element, of means at the outer end of the adjustably tensioned against the under sur-- face of the cap member.

2. In combination, a hollow cylindrical chamber adapted to contain a chemical element, of means at the outer end of the chamber adapted to admit air over the chemical element, the said means comprising a removable threaded cap member having air admitting ports and which is provided at its center portion with a threaded stem, terminating at its outer end in a handle, and carrying on its inner end a .removable spring member, a valve member disposed between the spring and the cap whereby the valve element may be adjustably tensioned against the under surface of the cap member.

3. An attachment for gasoline engines comprising a tubular member exteriorly threaded adjacent each end, the bore of said body restricted at one end and said restricted bore communicating with the main bore by a plurality of small flaring passages communicating With the main bore about its periphery, a closure cap adapted to engage the threads on the other end of the body, said cap having air inlet ports and a centrally located stem in threaded engagement with the cap, a disk adapted to seat over said stem and against the inner face of the cap and spring mounted on the inner end of the stem to resiliently force the disk to its seat substantially as specified In testimony whereof I aflix my signature.

JOHN BIRD.
